Smith Thompson (January 17, 1768 – December 18, 1843) was a US Secretary of the Navy from 1819 to 1823 and a US Supreme Court Associate Justice from 1823 to his death. Early life and the law Born in Amenia, New York, Thompson graduated from Princeton University (then known as the College of New Jersey) in 1788, taught for a short period thereafter, then studied law under James Kent and subsequently set up a law practice. He practiced in Troy, New York from 1792 to 1793, and in Poughkeepsie, New York from 1793 to 1802. Smith Thompson's father Ezra Thompson (1738-1816) and grandfather Samuel Thompson (1696-1768) were part of a family group that moved from New Haven, Connecticut to Dutchess County, New York by the time of the Revolution.

He would withdraw from his presidential campaign when outcompeted by other candidates. Thompson only reluctantly accepted his recess appointment to the United States Supreme Court from President James Monroe on September 1, 1823. He was to fill a seat vacated by Henry Brockholst Livingston. Formally nominated on December 5, 1823, Thompson was confirmed by the United States Senate on December 9, 1823, and received his commission the same day. Throughout his time on the court he was a staunch opponent of Chief Justice John Marshall. In a move now considered unusual, but then quite common, Thompson continued his political ambitions by running for other political offices while still on the bench. However, his 1828 bid for Governor of New York was unsuccessful, unlike the example of Chief Justice John Jay, who successfully ran a three-year campaign while still a Justice, ultimately winning election as New York State governor in 1795.
